To all 'whom 'it 'may concern: v

Be it known that I, HERMAN J. SULZEN, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, j

have invented certain new and useful Imgrovements in vCombination Speedographs,

peedometers, and Cyclometers, of which the following is a specification.

My invention relates to devices known as speedographs or speed-recorders desi ed for the purpose of recording the s eed o a moving automobile, carriage or ot er vehicle. The object of my invention is to provide a mechanism of the character mentioned, which' when correctlyl attached to a vehicle will be adapted to record the speed of the vehicle continuously upon a paper tape, and also one which'will record the time and position of the vehicle continuously, indicating whether the latter be inside or outside of the city limits, hence to provide a mechanism adapted to keep an accurate and exact s eed record of an automobile or other vehic e,for say, an entire year upon the-.same roll of tape. j

A further object of my invention is to pro-Y vide a mechanism of the character. men` tioned, which besides being a speedograph, will also act in the capacity of a lspeedometer, cyclometer, and a time-piece.I

Astill further object of my invention is to povide a mechanism as stated, which' will of a durable and lastingconstruction, and one which will be of the highest possible 'efficiency.

Other objects will appearhereinafter.

With these objects in view, my invention consists in al mechanism characterized as above mentioned, and in cert-ain, details -of construction and arrangement of parts all as `will be hereinafter fully described and particularly pointed out in the claims.

'M invention vwill be more readily understood .by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is afront elevation of .in device in its preferred form, Fi 2 is a si e eleva- 'tion thereof, a rtion o the casing of the same being bro en away so as to ex ose an `underlying'part of the mechanism, ig. 3 is an enlarged top plan view thereof, the speedf ometer roper being broken away so as V,to expose lv `lie underlying parts, Fig. 4 is a vertical longitudinal section taken oli substantially th .line :v -w ofFig. 2, Fig. 5 is aview similar to that of Fig. 3, except that'the top casing portion is removed so as to expose the mechanism lying beneath the same, Fic'. 6 is a vertical transverse section taken substantially on the line y-y of Fig. 4, Fig. 7 is a vertical transverse section taken on substantially the line .e--z of Fi 4, and Fig. 8 is anY enlarged sectional detai taken on substantially the line lw-fw of Fig. 7

Referring now to the drawings, 1 indicates a suitable metal casin 'in which is compactly mounted or assemble m mechanism. Vertically extending, and su stantially centrally positioned and rotatably mounted in bearings 2 and 3 in said'casing 1, is a shaft 4. The

Adownwardly, that is, exteriorly projecting end portion 5 of said shaft 4 may be operatively connected in any ordinary or preferred manner, pssibl by a flexible shaft, to one of the wheels ofy the vehicle'upon which the device is to be used. SaidV shaft is provided with a worm 6A at substantially the central portion thereof. In mesh with the worm 6 of said shaft 4 is a worm-wheel 7, the latterv being fixed upon a horizontally disposed shaft 8, the extremities ofthe latter being, mounted in bearings provided in the front 1 and rear walls ofthe casing 1. 9 indicates a pin projecting from and formed integrally with said worm-wheel 7.

10 isz a spring-cam lever, the end portion 11 of the same being suitably secured to the4 side wall 12 of the casing 1, the opposite end portion `13or cam-formed portion proper of said lever 10 being in the 'direct path of said pin 9.

14l indicates a connecting rod, the lower extremity of which is pivotally secured to the. lever 10, the upper extremity thereof being Said. cyclometer is of'any vsuitable ordinary or* preferred construction,

pivotally connected to the actuating arm 15 of a cyclometer.

the same being contained Within a casing 16 which is suitably mounted in the upper left-hand portion of the casing 1 projecting outwardlyl therefrom. By this' arrangement with every rotation of the worm-wheel 7 it is evident that the cam-lever 10 will be raised, thereby through the medium of the connect-v ing rod 14 andthe arm 15 the actuation of the cyclometer will obviously be facilitated', and which because of the worm-wheel 7 being 'so proportioned as to pass through one revoluti n every one-tenth of a mile of travel of the-vehicle, will indicate the distance traveled to tenths of a mile. The upper end portion 17 vof the shaft 4 lic is preferably decreased in diameter as shown. Slidably mounted upon said shaft portion 17, but fixed a ainst rotation thereon, is a circumferentia ly channeled, cylindrical mem# ber 18, the lsame being normally held in a position at the upper extremity of said shaft portion by the resilienc of coil-springs 19, the same being suitab y secured at their lower extremities to said member .18 and at their upper extremities to arms 20 fixed to and projecting from the upper extremity of the shaft 4.

21 indicate horizontally` disposed guide rods, the inner extremities of the same being xed inthe shaft 4 preferably just below the portion 17 thereof so as to oppositely project therefrom'. Slidably mounted upon. said rods are weights 22. Cords 23 having their opposite extremities connected respectively to the under surface of the member 18 and to the weight members 22, and passing under rollers 24' provided and rotatably mounted upgn the shaft 4 for this purpose, serve as a means Aofoperatively connecting said 25 weights and said member 18. Loosely rest- 1ng in the channel of said member 18, that is, so that the latter may `rotate therein, is a connecting member 25, to the portion 26 of Y.which is suitabl fixed the lower extremity of a vertically dlsposed rod 27. In swiveled connection with the horizontally disposed upper extremity 28 of .said rod 27, are the lower extremities of a pair of connecting rods 29.

30 indicates a ,preferably circular metal casing, which is provided with any suitable illuminating means, preferably an electric light 30. The depending tubular portion 31 of said casing 30 is revolublyl mounted in an upwardly extending tubular portion 32 of the casing 1. Either side of said casing 30 is provided with an outer cover or shiel glass 33 and an inner` glass 34 u on which is arranged a speed-indicating sca e 35. Suitably ositioned and havin its extremities suit-ab y mounted in the shield glass 33,' as clearly shown in Fig. 6, is a horizontally disposed -shaft 36. Rotatably mounted upon said shaft are sleeves 37 to the outer extremities of each of Awhich is fixed 'an indicator orrhand\38. Formed integrally :with said sleeves and oppositely projecting ina sub` stantially horizontal plane therefrom, are arms 39 to the outer extremities of which are pivotally connected the upper'extremities of lthe before-mentioned rods' 29.- A

With an arrangement as just described, .it is evident that as the shaft 4'isv revolved the weight members 22 because of 'their eeni 6o trifugal force willhave a tendency to travel in a larger radius, hence, will draw the member 18 downwardly against the tension of the springs 19. In so doing, the rod 27 is lowered, which in turn through the medium '654 of the connecting rods 29 actuates the indicators op hands 38 of the speedometer. The weight members 22, by such-an arrangement, obviously act as a governor for the speedometer, it bein evident that the centrifugal force of sai weights which is in va direct ratio to the speed of the vehicle, governs the radius of the circular path ofsaid the position of the member 18, the rods 29, and finally that of the indicators or hands 38.

40 indicates a preferably rectangular chamber, preferably formed of sheet metal, the same being located, as shown, in the rear upper left-hand portion of the, casing 1. Sald chamber is of such dimensions as to be adapted to receive a pad of tape 41.

42 and 43 indicate rollers, the same being provided with a coating of a suitable frictional material, preferably rubber, for reasons which will be obvious as 'the descri tion proceeds. The Shaft 44 to which the rol er 43 11s fixed, is mounted at one extremity in the rear Wall of the casing 1, the opposite extremity thereof being mounted in the wall 45 of the ta e-pad chamber 40. The Shaft 46 -of the ro er 42 is mounted in a swinging fork 47 depending fromthe top wall of the casing 1. A screw 47 .threaded in and projecting through the top wall of the casing 1, the lower extremity ofthe same engaging the extremity of an arm -47 formed integrally with one of the arms of the fork member 47, obviously facilitates keeping said rollers The tape leadin from the chamber 40 passes over the ro er 42, then'ce between the latter and the roller 43, thence under the roller 43. From the latter roller it passes over a horizontally disposed, preferably metal table 48,. suitably fixed as by screws .or rivets 49 to the rear wall of the casing 1, thence over an angular guide plate 50 also secured preferably by screws or rivets 51 tol the rear wall of the casing 1. Whence it passes downwardly close to the right-hand wall of theV casing 1 to and under a roller 52, which is fixed to a shaft 53 the extremities of which are rotatably mounted in the front and rear walls of the casing'l. After passtweei'i the roller52 and a similar rubber covered roller 54 and over the latter. The extremities of the shaft 55 of said roller 52 are mounted in a' fork 56, the latter bein swingingly mounted upon the bottom wa 57 o `the casing 1. A leaf-springf58 provided on the casing bottom 57 so that the `tremity of an arm 59 formed integrally with and projecting from one of the arms ofthe fork 56, serves as a means to keep said rollers 52 and 54- in close contact with each other. Whence the tape passes to areel 60 upon 'which it is coiled. Said; reel 60 is 42 and 43 in close contact with each other.

revolving weight members, and consequently ing under said roller 52, said tape passes becontact therewith, for obvious reasons. AA

gear-wheel 61 fixed toa shaft 62, the latter having bearings-in the front and rear wallsof the casin 1 and being spring driven, 63 indicating te driving spring casing, said gear-wheel 61 meshing with a reducing pinion 64 which is formed integrally with a gear-wheel 65 the latter being mounted upon a shaft 66, and inv mesh with a pinion 67 fixed to the shaft 53 serves as a means of driving said rollers 52 and 54, hence, forms the means of drawing `the tape through the mechanism in the manner as before described. While passing over the table 48 the saidtape is operated upon by a perforating needle'68 which is adapted to provide said tape with a series of perforationsthe same being adapted to gra hically indicate the speed of a vehicle. aid tape is also operated upon by jtwo additional pencils 69 and 70, the same beingl adapted to contact and graphically indicate, respectively, upon said tape, the time of day and the location or place, whether inside or outside of thecity limits of the vehicle. The principal function of the remainder of the mechanism is to operate said needle'68 and pencils 69 and 70.

Suitably mounted in the upper right-hand corner of the casing 1 and progecting slightly forwardly therefrom is a casing 71,.in which is 4contained an ordinary clockwork. The central arbor 72 of said clockwork projects rearwardly from the casing 71, as clearly shown in Fig.7. Fixed to said arbor 72 close to the casing 71 is a lcircular disk 73, the same being provided with a tapering notch 74 in the periphery thereof for a purpose hereinafter described. 75 is a pinion mounted upon said arbor 72, the same being formed' integrally with the disk 73. .ln mesh with sald pinion 75 is a gear-wheel 76, the latter being fixed u on a horizontally disposed shaft 77, rotatab y mounted in bearings in the clockwork casing 71.

78 isa pinion xed to the extremity of the shaft 77. Loosely mounted uponthefarbor4 72 in mesh with said pinion 78 is ak gearwheel 79. Said gear-wheels and pinions are so proportioned that the gear-.wheel 7 9 passes through one revolution to twenty-four of the disk 73 for a purpose hereinafter described. Formed integrally with or soldered to said gear-wheel 79 is an inwardly flanged diskl I 80. vSaid disk 8O is of a diameter slightly less than that of the disk 73 and is provided upon its periphery with notches 81 and 82, the same being of different depths and ositioned." diametrically opposite thereon or a pur ose hereinafter stated, Vertically exten ingy and slidably mounted in guides 83 Aupon the rear face of the casing 71 directly over the arbor 72 is a T-shaped mem.

therewith by means of a coil spring 89, the

respective extremities of the latter being fixed to the casing las at- 90 and to the upper extremity of a vertically disposed arm 91 whose lower extremity is fixed to the bellcrank lever 86. Pivotally secured as at 92 to a block 93 formed upon the under surface of the top wall of the casing 1 is a spring pencil arm 94v to the outer extremity of which is 'secured the before-mentioned pencil 69, said spring arm being adapted to keep said pencil 69 in constant contact with the surfaceJ of the tape. A lin'k 96 the extremities of which are respectively secured to said spring arm 94 and to the vertically extending end portion 97 of the bell-crank leverI 86, serves as a. means of operatively connecting said last-mentioned parts. VVh'en the device is in operation the disk473 which as before described, is driven by the'central arbor of the clockwork, hence, passes through one revolution an hour. As the notch 74 in said disk 73 is brought opposite the arm 85 of the member 84, that 1s, so as to be adapted to registertherewith, said arm 85 will obviously drop therein, the outer extremity thereof in which event will rest upon the periphery of the disk 80. By this action the bell-,crank lever 86 because of the tension of the coil-spring 89 will be partly revolved, and consequently will impart lateral movementto the pencil .69 which operates' upon the tape providinvr the same with a marking similar to those indicated by 98 shown in Fig'. 3.- As before stated the disk 73 passes through one revolution each hour, hence, ,at

The disk 80 which as ment of the member 84 when the latter is :resting in the notch 74 travels 1/24th as fast as the disk 73 as before described, hence,

passes through one revolution every twentyfour hours. By providing the periphery of said disk 8O with the notches 81 and 82 as beforementioned, as each of the said notches are brought opposite the arm 85 of the member 84 the latter will necessarily be permitted to drop farther than when resting in the notch 74 as before described, hence, allowing of greater movement of the pencil 69, consequently providing the tape with a longer marking 99 as shown in Fig. 3. arrangement a longer marking will be recorded every twelve hours. By-m'aking said By t islthe end of each hour a marking as 98 will be .i made upon the tape. before stated limits the downward movenotches 81 and 82 of different depths, it is evi-dent that the distinguishing between, say 12 oclock at night and 12 oclock at day, may readily vbe facilitated.

Iivotally mounted in a bracket 100 secured to the front. wall 0f the casing 1 is a bell-crank lever 101. 102 of said lever is forked, as shown, for the reception of a pin 103 projecting from and formed integrally with themember25. Pivotally secured as at 104 to the block 9?) is a spring needle supporting arm 105 tothe outer extremity of which is secured the said needle 08, said arm being adapted to normally keep the point of said needle just above the surface of the tape for obvious reasons.

68 indicates a circular slot provided in the table 48 for the reception of a needle ,point when passing through, that is, when perforating the tape. Formed integrally with said arm 105 and preferably extending parallel therewith is an arm 106. A link 107 the extremities of which are respectively secured to said arm 106 and to the upper extremity 108 of the bell-crank lever 101 serve as meanskof operatively connecting said arm 10G, hence the needle .supporting arm 105 and the bellcrank lever 101. In order to facilitate vibrating said arm 105 which obviously is necessary in order that the needle be adapted to puncture or perforate the tape, I provide a concave edged metal plate 109 rotatably mounted in bearings provided in the rear wall or the casing land in a bracket 110 projecting from and formed integrally with the table 48. The concave edge portions of said plate 109 are adapted, as clearly shown in Fig. 5, to engage the eX- tremity of the needle supporting arm 105, hence, with each revolution of said plate said arm will be vibrated twice, thereby causing two perforations to be made by the needle in.the tape. In order to facilitate driving said plate 109 I provide the same with a gear-wheel 111 at one extremity thereof, which through the medium of a train ofgears 112 rotatably mounted upon the rear-wall of the casing 1 will be driven from a gear-wheel 113 fixed to the shaft (32, by the spring provided upon the latter.

By an arrangement as just described, it is obvious that the position of the bell-crank lever 101 and therefore the needle G8 is under the government of the same means as governs the position of the indicators or hands 38 of the speedometer as before described, said needle (38 being moved in an arc with the pivotal point 104 as a center, transversely across the tape. By the provision of the needle adapted to operate and perforate the tape as stated, that is, without a constant' contact therewith, all possibility of any impediment in the correct movement of said needle and said tape is eliminated. Secured as at 114 to said block 93 and prefer- The lower extremity ably positioned between said arms 94 and 106 is a spring arm 115 t0 the extremity of which is secured the before-mentioned pencil 70. Said spring arm 115 is adapted to normally keep said pencil from contacting the tape, in which case a projection 116 formed integrally with said arm and which is adapted to rest against the lower edge of the depending tubular portion 31 of the casing 30 rests in a recess 117 provided in said lower edge of said tubular portion 31, as clearly shown in Figs. 4 and 0. By simply rotating the casing 30, said projection 116 will obviously be forced out of said recess 117 whereupon it will be lowered hence, forcing said pencil down into contact with the paper. My idea is to'have the inner glasses 84 of the casing 30 stained different colors, that is, say for instance have one white and the other red. Then inside the city limits the white light, that is, the white glass is to be` faced forwardly, in which position the projection 11G will be resting 1n the recess 117, hence, the pencil will not operate upon the tape. Then outside the city limits, the red light is to be shown, in which case said projection will not be resting in said recess, hence said pencil will contact the tape, indicating that. the vehicle is outside of the city limits.

VIn order to facilitate a regular and steady feed of the tape through the mechanism, I provide the arbor 72 with a doubled flanged sprocket-wheel 11S loosely7 mounted thereon and preferably positioned between the disks 73 and 80, as clearly shown in Fig. 7, the flanges 119 andy 120 thereof being each provided with ratchet teeth upon the peripheries thereof.

121 indicates a pawl mounted upon the disk 73, the same being adapted to be held in engagement with the ratchet teeth in the flange 119 by means of a leaf-spring 122.

By providing the shaft 44 of the roller 43 with a sprocket-wheel 123, and by connecting the latter with the sprocket-wheel 118, by a chain 124, it is obvious that the escapement of the tape will be governed by the velocity of the arbor 72 of the clockwork, hence, will be regular and steady.

By employing a device as thus far described, just as much tape will be used when the vehicle is at rest as when the same is in motion thereby resulting in a waste of tape and necessitating the storing in the device of a comparatively large amount of tape, hence, resulting in a device too spacious to be conveniently used and thereby decreasing the practical value of the device. iith the obviation of this objection in view, I provide the gear-wheel 79 with an outwardly iianged collar or sleeve 125 fixed thereto in any suitable manner, but preferably by being grazed or sweated upon a cylindrical projection 120 formed upon said gear-wheel. Having one o 946,170 e ,j

of its extremities fixed in said member 125 and the other extremity thereof journaled upon a cylindrical projection 127 formed upon the inner surface of the rear wall of the casing 1, as clearly shown in Fig. 7, is a i tubular member 128, the same beingin axial alinement with the arbor 72. Longitudinally extending within said tubular member 128, the same being pivotally secured therecsi;

in as at 129 is a lever 130. Pivotall secured to the other extremity of said liever 130 is a radially extending rod 131, the same passing through a slot or perforation provided in the sleeve member 125.

132` indicates a pawl fixed to a shaft'133 the latterbeing rockingly mounted in the gear-wheel 79 and the disk 80, as shown in Fig. 7 Said pawl is adapted to engage the teeth in the flange 120 in the sprocket-wheel 118 and is normally held in engagement therewith by a coil-spring 134 which is fixed at one extremity to the gear-wheel 7 9, the other extremity thereof engaging an arm 134 fixed toand projecting from the shafty 13 5 indicates a link oneextremity of the same being fixed to the shaft 133,- the other extremity thereof beinfg ivotally secured -to the upper extremity o t provision it is obvious that by depressing ythe lever 130 causes the disengagement of said pawl 132. When said pawl 132 is in engagement -with said ratchet teeth, it is evient that the escapement of the tape is overned by thevelocity of the gear-Whee 79, hence, is just 1/24th as great as when said pawl is not in enga ement Iwith said ratchet teeth, as in the atter case it is obviously governed by the velocity of the disk 73, it being my object to decrease the tape escapement at just this ratio as when the vehicle is at rest. In order therefore to facilitate depressin saidlever 130 when the vehicle is at restfl provide the tubular member 128 with a slidable sleeve 136, and form said lever 130 with an obliquely edged projection 137 the latter extending through a longitudinal slot provided in the member 128 for the reception of the same.l

138 is a bell-crank lever pivotally mounted as at 139 to a support 140. The end portion 141 of said lever is forked, as clearly shown in Fig. 8, for the receptionof-a pin 142 projecting from ,and formed integrallywith the rod 27. The opposite end portionr .143 of said lever is provided with`an in- Ategral arched double fork 144, Athe main arms 145 being adapted to receive the sleeve 136; as shown in Fig. 8, the auxiliary fork arms 146 being adapted to receive pins ../147 .formedupon and projecting outwardly i vlset or ob 1 uely disposed as at 148 the exle ltr'einities t ereof adapted to be in,v

from lo posite Apointsu on the sleeve 136. The/en ortions of sai arms 146 are off-v e rod 131. Byv this.

constant contact with the outer surface of the flanged portion of the member 125, as clearlyshown in Fig. 5. By this arrangement as the vehicle moves moi'evslowly and finally is brought to a stop thereby causing the rod 27 to be raised, the end portion 141 of the bell-crank lever 138 will also be raised, hence, causing the forked end portion 143 thereof to lbe lowered, in which event, vthe sleeve136 will be moved down the member 128,thereby releasing the lever 138, which when the vehicle was in motion was obviously depressed, as shown in the drawings, bythe sleeve 136 which in the latter case was in engagement with the projection 137, and Whiehin turn allows the `pawl 132 to engage the ratchet teeth in the flange 120 in the s rocket 118 with .a

'result as before describe Thus the escapement of the tape is automatically governed according to the need for it.

' A weight 149 ad'ustably secured in a lon 'tudinally exten ing slot 150 provided in t e end portion 143 of the lever 138 obviously acts in the capacity of a speedequalizer for the governor weights 22 when it is taken into consideration that the centrifugal force of a revolving body, in this case the weights 22, increases directly as the radius in which it moves and also as the square ofthe number ofspeed revolutions. l

151 indicates a cover glass the same coverin-g an opening or slot 152 in the top and side of the casin 1 by means of which the marked tape wil be clearly visible from without, and also making vit possible to lreadil observe the speed record of the vehicle or two or three days previous.

While I have shownHwha-t I deem to be.

the preferably form of my device, I do not wish to Vbe limited thereto as it is obvious there might be many changes made in the details o construction and arrangement of parts without departing from the spirit of my invention.v
